Fruit and vegetables have been identified as a vital key to mental well-being by researchers in Queensland, challenging nutritional recommendations around the world.

Their study suggests that eating eight or more portions of fruit and vegetables a day not only leads to better physical health but improves mental well-being.

The study, by health economics researcher Dr Redzo Mujcic of Queensland University’s school of pharmacy, involved more than 12,000 Australian adults.

A happy life

Mujcic found participants were at their happiest when they ate five portions of fruit and four portions of vegetables each day.

The results showed that the optimal consumption bundle is around four serves of fruit and four serves of vegetables a day for most well-being measures, and that less than 25% of Australian adults consume this quantity​,” he said.

He said the study challenged healthy-eating guidelines promoted by many governments around the world.

Many public health messages, such as the World Health Organisation guidelines, promote the consumption of five serves of fruit and vegetables daily​,” he said.

While the combined portion of eight or more may seem relatively high, the present findings are closely in line with recent studies from the UK and New Zealand​.

Our research indicates that current guidelines are in need of review​.”

The research found that well-being benefits derived from eating more fruit and vegetables were much higher for women than men, and that solely eating fruit had a greater impact on overall mental health than eating vegetables.

Age-old question

Mujcic said he used data from the annual household, income, and labour dynamics survey to answer the age-old question of wether fruit and vegetables are good for us and in what quantity.

The data has been collected from the same set of individuals, aged between 15 and 93, over a two-year period on their dietary and lifestyle choices, along with a number of mental and physical health measures​,” he said.

With this data, we have been able to use much richer statistical methods to answer these types of questions​.”

Study participants were asked to rate their level of happiness and record their daily consumption of fruit and vegetables.

Mujcic said large-scale randomised control trials were needed to better inform existing public health messages and social policy.

One portion is the equivalent to one piece of fruit or vegetable the size of the palm of your hand.
